Hi Nick,
I don't think it's just bad luck, I really think there is a problem.
I managed to grow plantains and parsley from splicing plants in a greenhouse, no issue. I realise these are not rare.
I cannot grow dragonfruit, bonsai buds, pomegranite or birds of paradise. I haven't tried the other rare ones because I don't have the base plants needed yet. It's been well over 50 sim days, four seasons and I've tried two different games with two different sims and two different growing situations
- I've tried in a green house and out of a greenhouse
- my greenhouse walls are maximum height so trees are growing fine
- i have a thermostat in the greenhouse, I've tried with and without the thermostat
- I have lots of beehives
- I've tried splicing both types of plants (i.e. for dragonfruit I tried splicing a snapdragon onto a strawberry plant and grafting a strawberry plant onto a snapdragon plant)
- the spliced plants show all 3 types of plants that can grow, but only the original spliced ones are growing (i.e. strawberries and snapdragons, cherries and apples)
- all plants are tended regularly and fertilised, some are of excellent quality
- my sim is level 10 gardening skill, level 9 botany career
I realise these three plants are rare, but they can't be "won't grow in 50 days" rare, that seems excessive.
